Abstract
A view order that matches k-space sampling to cardiac motion within the acq uisition window was developed for breath-hold three-dimensional contrast ma terial-enhanced coronary magnetic resonance angiography. In vivo experiment s in seven volunteers demonstrated that blurring was substantially reduced with this motion-matched view order as compared with the standard centric v iew order. Coronary arteries were well delineated.
